Till Rohrmann created FLINK-22597:
-------------------------------------
Summary: JobMaster cannot be restarted
Key: FLINK-22597
URL: https://issues.apache.org/jira/browse/FLINK-22597
Project: Flink
Issue Type: Bug
Components: Runtime / Coordination
Affects Versions: 1.12.3, 1.11.3
Reporter: Till Rohrmann
Assignee: Till Rohrmann
Fix For: 1.11.4, 1.12.4
Since we are reusing the {{DefaultLeaderRetrievalService}} for finding the
resource manager in the {{JobMaster}} and since the leader retrieval service
cannot be reused, it is not possible to restart the {{JobMaster}}. This causes
Flink to fail in case that the {{JobMaster}} regains the leadership in Flink
versions <= 1.12.
